Debunking Bidet Myths

In the market or just looking? If health concerns surrounding the globally popular toilet seat upgrade are stopping you from sealing the deal, pull up a seat. We’re going to debunk some common misconceptions about bidets.

Myth 1: Bidets use toilet water

Although bidets are hooked up to the toilet seat and the water appears to spray out of the bowl, the actual water supply is coming from the same pipes as your faucet and shower. Bidet water supplies are just as sanitary as drinking water from your kitchen sink, and there is no risk of contamination from used toilet water.

Myth 2: Bidets cause hemorrhoids

A common misconception is that the pressure of the water spraying from the bidet can cause inflammation and swollen veins in the anal region, also known as hemorrhoids. However, there has been no study that has shown a correlation between bidet use and the development of hemorrhoids. The painful inflammation is actually typically caused by straining during bowel movements, obesity and pregnancy – internal factors.
Bidets don’t cause hemorrhoids and can actually help treat them! Bidets have been shown to help heal hemorrhoids since they’re more gentle and provide a deeper clean than just wiping.

Myth 3: Bidets throw off internal pH

A big concern for those using bidets for feminine hygiene is the risk of upsetting vaginal pH. Douching products that contain iodine, vinegar, baking soda and other strong ingredients can throw the natural flora off balance and cause pain and infection. Because bidets spray clean water that isn’t mixed with any soaps or solutes, they are perfectly safe and a healthy way to achieve a deeper clean than one could using dry toilet paper.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
